Just opened mine, I think they were in my mailbox for a few days. They're great! only regret is that the 1.25's were sold out, and the 1.5's are designed for a lower row than my only 1.5 keys. Please re-run this one, and this time get like 4 times as many 1.25's!

Just wanted to provide an update. I contacted support and am receiving a full refund. This was handled very well, I think. If you get keys that don't fit even though the description said they should fit your keyboard, contact support. Faith in Massdrop = restored.

well, this is unfortunate. C'mon, Massdrop! You have GOT to get better pictures for these products! from the description page, there is almost no hint that these keys are dcs/oem profile bottom row! Granted they are shown on a bottom row, but the angles of the pictures gives no perspective on the angle. I bought these for the only led 1.5x keys on my ergodox and the profile is a disaster for those keys. I am tempted to contact support on this issue.
E: Well, they are a bit awkward orientation wise. To make the profile work, I had to arrange them to make the guy fall out of the "ceiling" and into the "floor". I did however just compile my own custom firmware tweaks so that those LEDs are more useful as layer indicators, which in a way forgives the circumstances a bit.

Bought the 1.5" option for my G710+, intending to replace the Windows keys like it shows in the photo. They only fit on ctrl. Pretty disappointed by this drop. Would have bought the other size if the photo had been accurate. Guess it's my fault for trusting the info provided.

I ordered the 1.5in because it said those were compatible with the "CM Storm Quickfire." Having a "CM Quickfire Stealth" I figured the size would match up, unfortunately not. These are too big for the ctrl/alt keys on my KB, and the angle of the keys are wrong for what they would fit, the tab and "\ |" keys. Oh well. I'll hold on to them in case I get a keyboard at some point in the future that they'll fit.
On the plus side, even though I can't use them, they sure do look nice!

I have a CM Storm Quickfire at home, and I bought the CM Quickfire Stealth massdrop (waiting for it to ship) for work. I also bought the 1.5" keycaps because it said they were compatible. It seems the incorrect description comes directly from Max's product page. On their own website it has the same information. Very annoying.
They do look great, but I can't use them! I'm upset that it won't fit in either of my keyboards, even though the description said they would. It will fit the TAB key on my Storm Quickfire, but who wants to do that?** And then you can't use both keycaps.
Not sure whom to be angry with :/ ...Going to be much more cautious with Massdrop from now on, and I definitely won't be using or recommending Max Keyboards. The money isn't a big deal, but waiting 3 weeks just to receive an incorrect product is.
**Edit: Nevermind, DavidGX is right. They fit the Tab and |\ keys, but they're angled strangely, so it is very uncomfortable to use.

I'm in the same boat. Judging by the proportions though, and looking at photos of the keyboards each size officially fits, it looks like we need 1x1.25s, and even those can only go on our CTRL and ALT keys, since the Poseidon has a non-standard bottom row.
What I don't understand is what the units of these measurements are. Because I just popped off my CTRL key, and none of the dimensions are anywhere close to a 1 in either inches or centimeters
